According to the cached copy of AT&T's bgp4policy.doc at:

http://www.onesc.net/communities/as7018/bgp4policy.pdf

You should just be able to setup BGP with a private ASN.  It's not  
quite what you asked for, but it should be "in policy" at AT&T.

I know we've run into providers that absolutely insist on a customer  
router even inside the provider's colo, and plenty more that don't.   
"Their network, their rules".

I'm assuming you have a switch connected to the ethernet handoff.  A  
lot of 1U switches now will do a little bit of layer 3 (including  
BGP) so it shouldn't necessarily add any equipment to your setup to  
accomplish this.

Ethernet handoff on one VLAN, your servers on the other... BGP  
session announcing your /24 with a private-as, and accepting default  
only (or dropping all routes and running with a static default,  
whatever floats your boat).
